Bi-amplified design with 2 high-output, Class-D amplifiers to separately power the FLEX array and 12-inch LF driver.
Exclusive flexible array can be configured into four unique shapes (“Straight,” “C,” “J” or “Reverse J”), allowing the customer to choose the best possible coverage pattern for the application.
2 input channels with independent volume controls and Line Level/Mic switch on Channel 1 | Wide, consistent coverage from an 8-driver mid/high line array, with each driver mounted on a custom 100° waveguide.

Power – 450 Watts Max x 4 @2-Ohms, 225 Watts Max x 4 @4-Ohms, 900 Watts Max x 2 Bridged @4 Ohms.
Class A/B Topology – Class ‘A’ amplifiers have enormous amount of current flowing through its output transistors with no audio signal. Class ‘B’ amplifiers have no current flowing through its outputs with no audio signal.
Full Range – With a Full Range amplifier you not only have the option to run your speakers, but also your subwoofers.
Mosfet Power Supply – A MOSFET is basically an electrical switch that allows the flow of electrical current. It controls the output voltage & current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry.
Variable Gain Control – The gain control is not for adjusting volume. It simply adjusts the amount of signal that is coming from your receiver and going to your amplifier.
Variable BASS Boost – With Variable Bass Boost you have the control of exactly how much BASS you want to pump out to your subwoofer(s).
Bridgeable – Dramatically increase the power output to you speakers and subwoofers by connecting two amplifier channels.
Specs – Dimensions: 13.5” x 10.31” x 2.25, Weight: 12 lbs..
